I am thinking about upgrading my 55gal to a 90 gal. My 55 is a mixed reef and is my first tank since in this hobby. I want to go sps dominant with some lps and zoos with the upgrade.

55gal:
Live rock
Live sand
octopus hob skimmer
hob fuge
powerheads
light: 6x54w t5's "Nova extreme pro"
With these lights iv been able to keep large verity of corals and even good growth on sps.

I am looking for a 90 gal reef ready tank so i wanted to know about equipment.

is 30 gal a good size for the sump?
What kind of skimmer should i be looking for?
Do i need to upgrade the lights? Iv seen some pretty good setups with t5's but are MH's going to be better?
What about water movement what kind of powerheads? I dont want to have 5 powerheads in my tank but also dont want to spend hundreds on vortechs. any alternatives? I know sps need a lot of flow.
What power return pump should i get within a reasonable price?

I also wanted to know whats the best sand for reef's and a sps tank? for my 55gal I use "Natures ocean bio-active live sand" that you can get from petco. This sand seems to blow around a lot, a little glass cleaner movement near the sand make a cloud.

If you have any pics of 90 gal i would love to see them to get some ideas.
Thanks for reading, any suggestions would be appreciated. I'm really serious about upgrading and want to get started asap

is 30 gal a good size for the sump? The bigger the Better 30 is good but if you can fit a larger sump the happier you will be
What kind of skimmer should i be looking for? that is a really broad question and I have not kept up on the new skimmers I have an MRC MR2 which is about 5 years old it works well but there are bigger and badder skimmers out now Coral vue has a good line with the REEF Octopus Pinwheel Skimmers so I hear but I really don't know enough about them I know a few folks have purchased them.
Do i need to upgrade the lights? Iv seen some pretty good setups with t5's but are MH's going to be better? I would say that with SPS Metal halide lights are going to be better, that being said there are a lot of folks out there now that keep sps with t-5, I had good luck with t-5's in my 60 gallon reef but I had no sps. currently I have 2 250w MH with my 150.
What about water movement what kind of powerheads? I dont want to have 5 powerheads in my tank but also dont want to spend hundreds on vortechs. any alternatives? I know sps need a lot of flow.
It's kind of one or the other unfortunately or you can plumb a closed loop system in the tank.

What power return pump should i get within a reasonable price? try to stay in the 8 - 10 times per hour but do not calculate this into your tank turn over rate with the power heads.

I also wanted to know whats the best sand for reef's and a sps tank? for my 55gal I use "Natures ocean bio-active live sand" that you can get from petco. This sand seems to blow around a lot, a little glass cleaner movement near the sand make a cloud. Sand is Sand and will be live sand after a while just make sure it is a calcium based sand not silica based sand.

the test is calcium based sand will dissolve and bubble when introduced to vinegar. silica based sand will not.

PS look at peoples build thread do a search for 90 gallon build threads and go from there. I would also look at large build threads too there is a lot of information and ideas to be had when you read others threads.
